Enhanced DRX and control channel

Abstract

A wireless device receives first configuration parameter(s) indicating that a first search space and a second search space are used together for reception of DCI and a second configuration parameter indicating a value of a DRX timer. The wireless device receives first DCI based on: monitoring in a CORESET based on the first search space and in first symbol(s), and monitoring in a CORESET based on the second search space and in second symbol(s) that are after the first symbol(s). The wireless device may start the DRX timer with the value in a third symbol that is after the second symbol(s).

What is claimed is: 
     
       1. A method comprising:
 receiving, by a wireless device from a base station:
 at least one first configuration parameter indicating that a first search space and a second search space are used together for reception of downlink control information; and 
 a second configuration parameter indicating a value of a discontinuous reception (DRX) timer; 
 
 receiving, from a base station, first downlink control information based on:
 monitoring in a control resource set (CORESET) based on the first search space and in one or more first symbols; and 
 monitoring in a CORESET based on the second search space and in one or more second symbols that are after the one or more first symbols; and 
 
 starting the DRX timer with the value in a third symbol that is after the one or more second symbols. 
 
     
     
       2. The method of  claim 1 , wherein:
 the first search space is associated with a first CORESET; and 
 the second search space is associated with a second CORESET. 
 
     
     
       3. The method of  claim 1 , wherein the DRX timer is a DRX inactivity timer. 
     
     
       4. The method of  claim 3 , wherein the wireless device is in a DRX Active time while the DRX inactivity timer is running. 
     
     
       5. The method of  claim 1 , wherein the first search space and the second search space are wireless device specific search spaces. 
     
     
       6. The method of  claim 1 , wherein the first search space and the second search space are common search spaces. 
     
     
       7. The method of  claim 1 , wherein a parameter in first configuration parameters of the first search space has the same value as a corresponding parameter in second configuration parameters of the second search space. 
     
     
       8. A wireless device comprising:
 one or more processors; and 
 memory storing instructions that, when executed by the one or more processors, cause the wireless device to:
 receive, from a base station:
 at least one first configuration parameter indicating that a first search space and a second search space are used together for reception of downlink control information; and 
 a second configuration parameter indicating a value of a discontinuous reception (DRX) timer; 
 
 receive, from a base station, first downlink control information based on:
 monitoring in a control resource set (CORESET) based on the first search space and in one or more first symbols; and 
 monitoring in a CORESET based on the second search space and in one or more second symbols that are after the one or more first symbols; and 
 
 start the DRX timer with the value in a third symbol that is after the one or more second symbols. 
 
 
     
     
       9. The wireless device of  claim 8 , wherein:
 the first search space is associated with a first CORESET; and 
 the second search space is associated with a second CORESET. 
 
     
     
       10. The wireless device of  claim 8 , wherein the DRX timer is a DRX inactivity timer. 
     
     
       11. The wireless device of  claim 10 , wherein the wireless device is in a DRX Active time while the DRX inactivity timer is running. 
     
     
       12. The wireless device of  claim 8 , wherein the first search space and the second search space are wireless device specific search spaces. 
     
     
       13. The wireless device of  claim 8 , wherein the first search space and the second search space are common search spaces. 
     
     
       14. The wireless device of  claim 8 , wherein a parameter in first configuration parameters of the first search space has the same value as a corresponding parameter in second configuration parameters of the second search space. 
     
     
       15. A system comprising:
 a base station; and 
 a wireless device comprising: one or more processors; and memory storing instructions that, when executed by the one or more processors, cause the wireless device to: receive, from the base station: at least one first configuration parameter indicating that a first search space and a second search space are used together for reception of downlink control information; and a second configuration parameter indicating a value of a discontinuous reception (DRX) timer; receive first downlink control information based on: monitoring in a control resource set (CORESET) based on the first search space and in one or more first symbols; and monitoring in a CORESET based on the second search space and in one or more second symbols that are after the one or more first symbols; and start the DRX timer with the value in a third symbol that is after the one or more second symbols. 
 
     
     
       16. The system of  claim 15 , wherein:
 the first search space is associated with a first CORESET; and 
 the second search space is associated with a second CORESET. 
 
     
     
       17. The system of  claim 15 , wherein the DRX timer is a DRX inactivity timer. 
     
     
       18. The system of  claim 17 , wherein the wireless device is in a DRX Active time while the DRX inactivity timer is running.
